| Output detail | Our workflowShows exact crop offsets and dimensions. | Proprietary workflowFocuses on resizing and cropping tools broadly. | TextFaker should expose more preflight data. |
| Creative tools | Our workflowMinimal, non-aesthetic controls. | Proprietary workflowBroader editing and design options. | PicMonkey is better for final creative polish. |
| Privacy | Our workflowSource file can stay in-browser. | Proprietary workflowOnline editor upload model. | Local handling is a useful alternative. |

Detailed research
Why Users Compare
PicMonkey is a familiar crop-and-resize editor. Searchers who only need to know whether Instagram will cut off a portrait can be served by a smaller, direct tool.
- Show center crop and custom anchor preview.
- Let users compare crop versus padding in one view.
- Add copyable result summary for content teams.
Implementation Notes
Because the tool's pass/fail criteria are numeric, avoid face detection or quality scoring in version one. Deterministic dimensions and crop bounds should be the test contract.
- Generated 800 x 1200 fixture should produce a 800 x 1000 centered 4:5 source crop in cover mode.
- Generated 1600 x 900 fixture should show large side crop in cover mode or top/bottom padding in contain mode.
- Output filename can append instagram-4x5 or instagram-1080x1350.
Demand Evidence
Public user discussions mention square frames, white borders, and manual crop practice, all of which are direct alternatives to automatic crop loss.
Content Boundary
Position as an alternative workflow to proprietary software, not a complete PicMonkey clone. This is important for accuracy and user expectation.
Research notes
- PicMonkey's official resizer page distinguishes crop from resize and says it supports social posts, photos, videos, and design projects.
- The page describes a free account/trial flow; TextFaker can offer a lower-friction local utility for this single job.
- Community feedback shows the need is practical previewing and preserving composition, not necessarily broader editing.
